Electronic structure of a heterotetranuclear copper(I)2-iron(II)2 complex bridged by p-accepting 2,2'-bipyrimidine. Close-lying but orthogonal frontier orbitals
The new complex I contains two 1,1'-bis(diphenylphosphino)ferrocene-coordinated copper(I) centers which are connected by the D2h-sym. p acceptor 2,2'-bipyrimidine (bpym). Cyclic voltammetry and ESR reveal a ferrocene-based HOMO and a bpym-centered LUMO. There is no detectable HOMO/LUMO absorption band because of orthogonality between the two types of orbitals. The lack of strong solid-state metal-ligand charge-transfer (MLCT) luminescence is an indirect consequence of the small bite angle of the bis(diphenylphosphino)ferrocene ligand, which cannot induce strong distortion at the copper center. on SciFinder(R)
